BACKGROUND OF THE PRESENT INVENTION Field of the Present Invention

The present invention relates generally to cable management systems fortelecommunications cables, and, in particular, to vertical cablemanagers that may be assembled quickly and with minimal tools.

BACKGROUND

Racks, frames, cabinets and the like for supporting computer and otherelectronic equipment are very well known. Similarly, raceways forrouting cables and wires to and from that equipment are likewise wellknown. In particular, a number of raceways have been proposed forrouting cables, wires and the like (generally referred to hereinafter as“cables”) vertically through or adjacent to equipment racks, frames,cabinets and the like (generally referred to hereinafter as “mountingfixtures”). Such raceways may be used to route cables vertically toequipment mounted or otherwise supported on a mounting fixture fromother equipment on the mounting fixture, from an overhead or underfloorraceway, or the like. These cables are generally routed in the verticaldirection to a point adjacent to the desired equipment and then routedin the horizontal direction to the desired equipment.

An important characteristic of such raceways is the presence of aplurality of openings in the sides of the raceway through which cablesmay be routed, thereby facilitating more convenient access between theequipment and the interior of the raceway. For example, U.S. Pat. No.2,921,607 to Caveney, U.S. Pat. No. 3,705,949 to Weiss,commonly-assigned U.S. Pat. No. 7,119,282 to Krietzman et al., and U.S.Pat. No. 7,285,027 to McGrath et al. each disclose a covered wiring ductor wireway which includes side walls having a series of finger-likeprojections separated by openings. The cables may be routed through theopenings by bending them around the projections, thus allowing thecables to be routed with relative precision, and preventing cables fromhanging loosely across the face of the rack itself A gap at the distalends of each pair of adjacent projections permits cables to be insertedinto each respective opening. The gap is narrower than the opening, thusaiding in the retention of the cables within the opening. The distalends of all the projections may then be covered by a cover, thusproviding further retention capability.

It is often advantageous to provide a cable raceway having a frontportion and a rear portion wherein two separate channels areestablished, either within the raceway itself or through the use ofadditional accessories. In such raceways, the separate channels arecommonly established by a partition or “midsection,” often withpassthrough openings therein. Until recently, such products utilized afixed midsection that is attached to the vertical side rails in oneposition only. The fixed midsection provides strength and rigidity tothe total structure. One downside of a fixed midsection is that itreduces cable capacity. Furthermore, installers find it difficult toposition cables front-to-back, and lashing bars and spools are notflexibly available. For example, U.S. Pat. No. 7,220,150 to Follingstadet al. discloses the use of spools, but the positions of the spools arerelatively fixed.

More recently, more flexible midsections have been provided. Forexample, midsection members that are vertically and horizontallyrepositionable and horizontally adjustable have been proposed incommonly-assigned U.S. patent application Ser. No. 12/350,216 to Garzaet al. However, assembling and disassembling vertical cable managersusing such midsection members is time-consuming and requires the use oftools, and the components themselves are expensive to manufacture.Furthermore, such cable managers and/or their components are bulky,making shipment more costly and otherwise problematic. Thus, a needexists for an improved vertical cable manager.

An opening into each cablering 68 is provided by a gap 69 between the ends of the crosspieces 67of each pair of adjacent projections 63. This gap 69 permits cables tobe inserted into the ring 68 by passing them sideways through the gap69, as described further in commonly-assigned U.S. Pat. No. 7,119,282 toKrietzman et al., the entirety of which is expressly incorporated hereinby reference.

FIG. 6 is a reverse side isometric view of one of the T-shapedprojections 63 of FIG. 5. The shaft 66 of the projection 63 utilizes areinforced construction characterized by a series of interlockingcrescent-shaped reinforcement walls or ribs 65. This geometry isdesigned to minimize deflection under load in the vertical, horizontal,and twist directions as indicated by the arrows in FIG. 6. The fingercross section is U-shaped which gives the greatest strength in thevertical and horizontal direction. The interior ribs are designed tominimize the twist and also to add strength in the vertical andhorizontal direction.

The respective projections 63 are evenly spaced along the length of thevertical support column 46 at a standardized spacing. In the embodimentshown and described, the spacing between the respective projections 63is equal to a single standard rack mounting unit (“RMU”)(conventionally, 1.75 inches), but it should be obvious that otherstandard spacings could be used such as spacings measured in alternativeunits or spacings which are multiples of the RMU. By using such astandard spacing, it is ensured that a cable ring 68 is disposed at, anddedicated to, each RMU along the height of a rack 20. Benefits of thisarrangement are further described in U.S. Pat. No. 7,119,282.

In at least one embodiment, the T-shaped projections 63 are integrallyformed with the vertical support column 46 using an injection moldingprocess. In at least some aspects of the present invention, however, theside cable guides 42 may be constructed according to the teachings ofcommonly-assigned U.S. patent application Ser. No. 12/350,216 to Garzaet al., which published as U.S. Patent Application Publication No. US2009/0236117 A1, the entirety of which is expressly incorporated byreference herein.

Because each cable guide 42 is formed separately from the midsectionmembers 80 and subsequently attached thereto, rather than being formedintegrally therewith, each cable guide 42 may be formed from a differentmaterial than the midsection members 80. Thus, although the midsectionmembers 80 may preferably be formed from metal, each cable guide 42 maybe injection-molded from plastic in order to create rounded or bevelededges along the edges of the T-shaped projections 63. Various advantagesof such an arrangement are described in U.S. Pat. No. 7,119,282.

Interconnection between the side cable guides 42 is provided by themidsection members 80. FIG. 7 is an isometric view of one of themidsection members 80 of FIG. 4. In the embodiment illustrated in FIG.4, two midsection members 80 are utilized in each vertical cable managerunit 32 and they are disposed near the ends thereof. However, it will beapparent to the Ordinary Artisan that, in at least some embodiments,greater numbers of midsection members 80 may be used, that they may bespaced evenly or irregularly, and that optional mounting locations maybe available, provided, of course, that appropriate mounting means andlocations are provided on the support columns 46.

FIG. 8 is an end view of the midsection member 80 of FIG. 7. Asillustrated in FIGS. 7 and 8, each midsection member 80 includes a web82 and two flanges 83,84, thereby forming a structure that is generallyI-shaped in cross-section. The web 82 is preferably penetrated by aplurality of mounting openings that may include pairs of slots 87,individual apertures 101, groupings of apertures (not shown), or thelike. In the illustrated embodiment, multiple pairs of slots 87 arearranged vertically along the length of the web 82, and a singleaperture 101 is included near the center of the web 82. However, it willbe apparent to the Ordinary Artisan that other arrangements may beprovided, such as any of those disclosed in U.S. Patent ApplicationPublication No. US 2009/0236117 A1.

Each midsection member 80 further includes a number of elements tofacilitate connection of the member 80 to a pair of the side cableguides 42, including one or more cable guide locking holes 81 near eachend of the web 82, an alignment slot 86 extending inward from each endof the web 82, and one or more cable guide alignment bosses 88 disposednear each end of the web 82. As described below, the alignment slots 86at the ends position the midsection member 80 within the socket 44 inthe cable guide 42 in the vertical direction by fitting over acorresponding shelf (not illustrated) provided in the back of the socket44 for that purpose. The alignment bosses 88 position the midsectionmember 80 laterally within the socket 44. The cable guide locking holes81 engage with cable guide locking tabs 47, described below, to retainthe midsection member 80 in the socket 44. The accessory attachmentfeatures (slots and hole) are for mounting optional accessories such ascable spools and cable lashing bars.

In an alternative not illustrated herein, midsection members comprisingtwo telescoping sections may be substituted for the fixed-lengthmidsection members 80 illustrated herein.

The midsection members 80 may be formed sheet metal; however, othermanufacturing methods could be used such as an extrusion. The flanges83,84 preferably have a formed closed profile that gives the member 80stiffness and also provides a smooth radius edge that prevents damage tocables that pass over the member 80, as perhaps best understood withreference to FIG. 8.

FIGS. 9 and 10 are isometric views of the midsection member 80 of FIG. 7being connected to the lower end of the side cable guide 42 of FIG. 5.As evident therefrom, the end of the midsection member 80 is receivedwithin the socket 44, whose cross-sectional shape corresponds to that ofthe midsection member 80. FIGS. 11 and 12 are cross-sectional views ofthe assembly of FIG. 10, taken along lines 11-11 and 12-12 respectively.As shown in FIG. 11, the socket 44 has a large taper such that the width36 of the slot 44 at the entrance is much wider than that of themidsection member 80, making it easy to insert the member 80, while thebase of the socket 44 is much narrower and is only slightly wider thanthe thickness of the midsection member 80. This geometry tends to holdthe end of the midsection member 80 securely within the socket 44.

As illustrated in FIG. 12, when the midsection member 80 is seatedwithin the socket 44, a shelf 43 located in the back of the socket 44 isinserted into the alignment slot 86, thus enabling the midsection member80 to be positioned vertically within the socket 44 with relativeprecision. The alignment bosses 88 of the midsection member bear oninterior walls of the socket 44, thereby enabling the midsection member80 to be positioned laterally within the socket 44 with relativeprecision. In order to retain the midsection member 80 in thisdisposition, a pair of locking tabs 47 are provided within the socket 44so as to interface with the locking holes 81 in the midsection member80. When enough force is exerted on the midsection member 80 relative tothe side cable guide 42, the end of the web 82 thereof is forced pastthe locking tabs 47, which are beveled for this purpose, and the lockingtabs 47 then snap into the locking holes 81, as shown in FIG. 11.

FIG. 13 is a fragmentary rear isometric view of a portion of the sidecable guide 42 and midsection member 80 of FIGS. 11 and 12. Asillustrated therein, a portion of each locking tab 47 extends throughthe body of the cable guide 42 and protrudes therefrom, where it may beaccessed by a user. By depressing the tabs 47, the catch portionsthereof are withdrawn from the locking holes 81 in the midsection member80. In this state, the midsection member 80 may be removed from thesocket 44.

With reference to FIG. 4, it will be appreciated that a single verticalcable manager unit 32 may be assembled by connecting two side cableguides 42 together using two midsection members 80 in the mannerdescribed.

FIGS. 15 and 16 are a profile view and an isometric view of an end ofone of the doors 38 of FIG. 4, shown in a partially disassembled state.As shown therein, each door 38 includes a center panel 70 and two edgepieces 71. The panel 70 may be of any shape but includes series ofoutwardly-extending tabs 72 along the edges thereof. Viewed in profile,each edge piece 71 includes a hinge structure 75, described in greaterdetail hereinbelow, as well as two fingers 73,74 that define a channelinto which fits a respective edge of the panel 70. One finger 74 ishooked to fit over and engage the tabs 72 along the edge of the panel70. Thus, each edge piece 71 may be attached to the panel 70 byinserting the panel edge into the channel defined by the fingers 73,74of the edge piece and snapping the hooked finger 74 over the tabs 72.The composite construction of the door 38 permits the edge pieces 71 andpanels 70 to be manufactured separately and from different materials. Inat least one embodiment, the edge pieces 71 are extruded plastic whilethe panel 70 is constructed of sheet metal. The composite constructionalso permits panels 70 of different widths to be used with the same edgepieces 71 to form doors 38 of different widths.

FIG. 14 is a profile view of an end of an alternative door 138 for usein one or more preferred embodiments of the present invention. Inparticular, the door 138 of FIG. 14 is a single piece, such as a singlepiece plastic extrusion. Such a construction, which utilizes a hingestructure 75 similar to that of the edge pieces 71 of the door 38 ofFIGS. 15 and 16, may generally be substituted for the composite door 38,but may be particularly suitable for cable managers of narrow widths.

Regardless of construction, the door 38,138 is mounted on the side cableguides 42 by snapping the hinge structure 75 onto the hinge bosses 76located on the ends of some of the T-shaped projection 63. This isillustrated in FIGS. 17 and 18, which are schematic top views of one ofthe doors 38 and two of the side cable guides 42 of FIG. 4, and FIG. 19,which is a fragmentary isometric view of an upper portion of one of thedoors 38 and one of the side cable guides 42 of FIG. 4. As showntherein, the hinge structure 75 includes two arms 77,78, defining ahinge channel 79, that may be snapped around the hinge bosses 76.Although the friction inherent in these couplings tends to support thedoor 38 at the proper height without need for vertical support, slippagemay be further prevented using stops 39, an example of which is shown inFIG. 19, inserted into the hinge channel 79 so as to bear on the tops ofthe hinge bosses 76 when the door 38 is installed at the proper height.The stops 39 may be of molded or extruded plastic and may be glued orotherwise affixed in place.

With reference to FIG. 19, the outer arm 77 of the hinge structure 75 isadapted to rotate around one side of the hinge boss 76 and includes ahook at its distal end that serves as a door retaining stop, while theinner arm 78 includes a structure having a semi-cylindrical innersurface adapted to rotate around another side of the hinge boss 76. Thedoor 38 is mounted on the side cable guides 41,42 by snapping the hingestructure 75 onto the hinge bosses 76. Once installed, the door 38 maybe opened along either side by unsnapping the hinge structure 75 of therespective edge piece 71 from the hinge bosses 76 and rotating the doorabout the hinge bosses 76 on the opposite side of the door 38. Thisrotation is illustrated in FIGS. 20 and 21, which are schematic topviews of the door 38 and one of the side cable guides 42 of FIGS. 17 and18. As shown therein, portions of the hinge arms 77,79 rotate aroundsemi-cylindrical surfaces of the hinge boss. As the door 38 is rotatedto the position shown in FIG. 21, it will be appreciated that the doorretaining stop at the end of the outer hinge arm 77 reaches a camlocated at the distal end of the hinge boss 76. When it does so, itsnaps into place, thereby holding the door 38 in place in that position.The force required to rotate the door 38 out of that position isintended to be relatively minimal such that a user may manipulate thedoor 38 easily to remain open or to be closed, as desired.

As shown in FIGS. 2A, 3 and 4, two or more vertical cable manager units32 may be stacked on top of each other to create a modular verticalcable manager 30 of greater length. This may accomplished using spliceplates 34 to connect side cable guides 42 together. FIG. 22 is anisometric view of one of the splice plates 34 of FIG. 4. As showntherein, the splice plate 34 is a flat, elongated structure having anotch 92 at each end. Each notch 92 includes at least one and preferablytwo locking catches 93 arranged therein.

FIGS. 23 and 24 are fragmentary side isometric views of the splice plate34 of FIG. 22 and one of the side cable guides 42 of FIG. 4. As perhapsbest seen in FIG. 23, the side cable guide 42 includes a plurality ofribs 94, forming a bed for receiving the splice plate 34, and aplurality of tabs 95 cover the bed for retaining the splice plate 34 onthe bed, thereby forming a receptacle for receiving an end of the spliceplate 34. An upright lock tab 96 is disposed at the inner end of thebed. To connect the splice plate 34 to the cable guide 42, the spliceplate 34 may be inserted beneath the tabs 95 and onto the ribs 94 of thebed. When the slot 92 in the end of the splice plate 34 encounters thelock tab 96, a beveled portion of one of the locking catches 93 forcesthe lock tab 96 to bend aside until the splice plate 34 is fully seatedin the cable guide 42, at which point the lock tab 96 snaps into placebehind the locking catch 93 as shown in FIG. 24, thereby locking thesplice plate 34 in place. The opposite end of the splice plate 34 may beconnected to the end of a second side cable guide 42 in the same manner.FIG. 25 is a side plan view of the splice plate 34 of FIG. 22 and two ofthe side cable guides 42 of FIG. 4, wherein the lock tab 96 of thesecond side cable guide 42 is being forced aside by the locking catch93. This construction facilitates the assembly of a cable manager 30without the use of any tools.

The splice plate 34 may be removed from either of the cable guides 42 bydepressing the respective lock tab 96, thereby removing it as anobstacle to removal of the locking catch 93, and pulling the spliceplate 34 out of the cable guide 42. The lock tabs 96 protrude slightlyfrom their surroundings to facilitate this purpose. Disassembly is thuslikewise achievable without the use of any tools.

Returning to FIG. 5, the rear accessory mounting holes 49 make itpossible to quickly and easily connect additional accessories to therear of the single-sided vertical cable manager units 32. FIGS. 26 and27 are fragmentary isometric views of a portion of the rear of one ofthe side cable guides 42 of FIG. 4, while FIG. 28 is a fragmentaryisometric view of a cable management accessory 50 being attached to apair of side cable guides 42, and FIG. 29 is a fragmentary isometricview of two such cable management accessories 50 mounted on the pair ofside cable guides 42 of FIG. 28. As perhaps best seen in FIGS. 26 and27, the rear accessory mounting hole is a slot of T-shaped cross sectionthat is arranged in the body of the vertical support column 46 and opento the side such that the head of a bolt 52 may be inserted into theslot in such a way that the shank of the bolt 52 protrudes from the rearof the column 46. When used with a hex-headed bolt 52 of the propersize, the head of the bolt 52 is restrained from turning when it isretained in the slot. Thus, as shown in FIG. 28, bolts 52 may beinserted into the mounting holes 49 on a pair of cable guides 42 suchthat their respective shanks may be used to mount an accessory 50, suchas a conventional cable ring, on the rear of the cable manager 30. Asshown in FIG. 29, a plurality of such accessories 50 may be attached ina column, thereby enhancing the cable management capabilities of theassembly.

Advantageously, the accessory mounting holes 49, which may be moldedinto the side cable guides 42 in an injection molding process, permitaccessories 50 to be attached quickly and easily by requiring only asingle tool, rather than two, to manipulate the bolt 52. This is becausethe head of the bolt 52 is imprisoned in the hole 49 and need not berestrained from turning with a separate tool. Furthermore, for anaccessory 50 like the cable ring shown in FIGS. 28 and 29, the spacingof the apertures 54 in the ring 50 prevents the bolts 52 from slidingout of the holes 49 once their shanks have been inserted through theapertures 54.

It will be appreciated that other accessories may be substituted for thecable rings shown in FIGS. 28 and 29.

The modular construction of the vertical cable manager units permitscable managers of a variety of dimensions to be constructed from alimited number of part sizes. Cable manager units 32 of multipledifferent widths may be constructed using the same side cable guides 32by substituting midsection members 80 of different lengths. FIG. 30 isan isometric view of a set of four midsection members 80,180,280,380 ofdifferent lengths, which in one commercial embodiment may includelengths of 6 inches, 8 inches, 10 inches and 12 inches. The third ofthese lengths (i.e., the 10-inch version) is featured in the verticalcable manager 30 of FIGS. 2A, 3 and 4, while the smallest of theselengths (i.e., the 6-inch version) is featured in the vertical cablemanager 130 of FIG. 33, discussed below. Other widths are likewisepossible as well. It will be appreciated, of course, that the width ofthe door 38 must likewise be changed, although as described previously,when the composite door structure is utilized, only the center panel 70needs to be changed; the edge pieces 71 are usable with any width centerpanel 70.

Cable managers 30 of multiple different heights (lengths) may likewisebe constructed using the same midsection members 80 by substituting sidecable guides 32 of different lengths. FIG. 31 is a side plan view of aset of two side cable guides 42,43 of different lengths, which in onecommercial embodiment may include lengths of 36 inches (3 feet) and 42inches (3.5 feet). When arranged on the basis of standard RMUs, asdescribed previously, the 36-inch length includes twenty T-shapedprojections (“fingers”) 63 and the 42-inch length includes twenty-sixT-shaped projections (“fingers”) 63. Thus, cable managers of either 36inches or 42 inches may be created using only a single cable managerunit 32, depending on which length is chosen. In addition, however,cable managers 30 of at least three different standardized lengths maybe created by pairing two cable manager units 32. FIG. 32 is a side planview of a three different pairs of side cable guides representing threedifferent cable manager heights (lengths). The pairing on the left is oftwo 36-inch lengths (6 feet total); the pairing in the center is of one36-inch length and one 42-inch length (7 feet total); and the pairing onthe right is of two 42-inch lengths (8 feet total).

It will be further appreciated that any of a variety of cable managementaccessories (not shown) may be installed in a cable manager unit 32 bymounting them to the midsection members 80. Examples of such accessoriesare described and illustrated, for example, in U.S. Patent ApplicationPublication No. US 2009/0236117 A1.

The various features described above contribute to a cable manager 30that is fast to assemble, requires minimal tools to assemble, and makesa small packaging footprint. The mounting of the cable manager 30 to arack 20 is faster since it requires only a single wrench; the mountingbolts are prevented from rotating by hex shaped holes 45 in the sidecable guides 42.

The cable manager units and resulting cable managers described so farare “single-sided” cable managers in that they include T-shapedprojections extending only in one direction, and thus comprise only onevertical cable trough for routing cables on either the front or back ofthe rack 10. FIG. 33 is an isometric view of a double-sided verticalcable manager 130 in accordance with one or more preferred embodimentsof the present invention. Like the single-sided cable manager 30, thedouble-sided vertical cable manager 130 includes one or more verticalcable manager units 132, each including a pair of side cable guides 142and one or more midsection members 80. The cable manager units 132 mayhave the same or different heights. In FIG. 33, two cable manager units132 are shown, each with a different height. The double-sided cablemanager also includes two doors 38, rather than one, because it includestwo vertical cable troughs. Two or more vertical cable manager units 132may be interconnected using a pair of splice plates 34.

The various components of the double-sided cable manager units 132 aresimilar to those of the single-sided units 32 except that the side cableguides 142 include T-shaped projections 63 extending both forwardly andrearwardly. Advantages and uses of a double-sided vertical cable managerare similar to those described in U.S. Patent Application PublicationNo. US 2009/0236117 A1. The side cable guides 142 also fail to includerear accessory mounting holes 49.

As described herein, the invention is disclosed in a verticalorientation. However, it will be appreciated that all or part of theinvention as described herein may be implemented in a horizontalorientation. For example, it is contemplated that the cable manager asdescribed herein may be implemented for use in a horizontal orientation.

Based on the foregoing information, it will be readily understood bythose persons skilled in the art that the present invention issusceptible of broad utility and application. Many embodiments andadaptations of the present invention other than those specificallydescribed herein, as well as many variations, modifications, andequivalent arrangements, will be apparent from or reasonably suggestedby the present invention and the foregoing descriptions thereof, withoutdeparting from the substance or scope of the present invention.
